DETAILED DESCRIPTION

Hereinafter, an embodiment of the present disclosure will be describedin detail with reference to the drawings.

A blood purification apparatus according to the present embodiment isapplied to a hemodialysis apparatus that performs dialysis treatment bypurifying blood of a patient which is extracorporeally circulated. Asillustrated in FIG. 1, the blood purification apparatus is mainlyconfigured to include a dialysis device 1 (dialysis monitoring device)having a blood pump 3, a substitution pump 4, a bypass connectorreceiver 5, a bubble detector 6 and an infusion pump 7; and a displaydevice 2 which is arranged above the dialysis device 1 and performs adisplay relating to blood purification treatment.

In the dialysis device 1, pipes such as a dialysate introduction lineand a dialysate discharge line (not illustrated) are formed. A dialyzer(blood purifier) is connected to the dialysate introduction line and thedialysate discharge line, and a blood circuit is connected to thedialyzer. Then, the blood circuit can extracorporeally circulate theblood of the patient and the dialyzer can purify the blood which isextracorporeally circulated.

The blood pump 3 is attached to the blood circuit (artery side bloodcircuit) and causes the blood of the patient to flow through a flexibletube configuring the blood circuit. The substitution pump 4 causes asubstitution to flow inside the blood circuit through a tube for thesubstitution. In addition, the bubble detector 6 detects a bubble insidethe blood circuit. The infusion pump 7 drives a syringe containing ananticoagulant (heparin) for example and continuously infuses theanticoagulant into the blood circuit.

In addition, the bypass connector receiver 5 receives and holds a bypassconnector. When the blood purification treatment is not performed, thebypass connector is connected to a tip of the dialysate introductionline (dialysate exit port) and a tip of the dialysate discharge line(dialysate returning port), and can short-circuit (connects the tips toeach other) the dialysate introduction line and the dialysate dischargeline. Then, when short-circuiting the dialysate introduction line andthe dialysate discharge line, the bypass connector is held by the bypassconnector receiver 5. Therefore, if the bypass connector is held by thebypass connector receiver 5, a switch reacts, thereby enabling detectionthat the dialysate introduction line and the dialysate discharge lineare short-circuited.

The display device 2 is a touch panel (for example, touch panel such asa color LCD) which enables a predetermined input by touching a switchunit displayed in a desired position on a screen. The display device 2can switch and display a plurality of screens including an alarm screendisplayed due to alarm issuing. More specifically, as illustrated inFIG. 2, the display device 2 can switch and display screens A to F. Forexample, when the screen B is displayed in a standby state before bloodpurification treatment, the display device 2 displays an operationscreen a which enables a predetermined operation through an inputoperation by touching a predetermined switch unit displayed on thescreen B. Alternatively, when the screen C is displayed during the bloodpurification treatment, the display device 2 can switch to a screen ddisplaying a numerical value of parameters of a monitoring subjectrelating to the blood purification treatment or a screen d displaying agraphic indicating development of the parameters of the monitoringsubject relating to the blood purification treatment through the inputoperation by touching a predetermined switch unit displayed on thescreen C.

That is, on the screen switched and displayed on the display device 2,various information items relating to the blood purification treatment(various setting values during the blood purification treatment,monitored values indicating current values of the parameters of themonitoring subject, or graphics indicating time-dependent variations)are displayed. Based on these information items, the treatment can beperformed. In this manner, in addition to the display relating to theblood purification treatment (for example, a variation rate ofcirculating blood volume (ΔBV) which is an index indicating a conditionof a patient under treatment or a graphic display indicating thetime-dependent variations in the venous pressure), the display device 2according to the present embodiment enables an input operation forsetting or changing the parameters relating to the treatment (forexample, drive speed of the blood pump 3 or drive speed ofultrafiltration pump not illustrated)).

During dialysis treatment (blood purification treatment), the displaydevice 2 according to the present embodiment can display the followingitems. That is, the display device 2 can display icons for variousoperations, such as an operation status (in a HD operation), variouspressure values (venous pressure and dialysate pressure),ultrafiltration conditions (ultrafiltration volume integration,ultrafiltration volume setting and ultrafiltration speed), dialysateconditions (dialysate temperature, dialysate concentration and dialysateflow rate), an anticoagulant infusion speed (IP speed), a blood flowrate, elapsed time of dialysis treatment, and blood pressure/pulsevalues.

Here, in the present embodiment, an alarm is issued to call attention ifthe blood purification apparatus detects an abnormality, such as whenwork relating to the dialysis treatment (operation for the dialysistreatment and operation for preparing the treatment) is carried out,when there is an operation mistake or erroneous setting, or for example,when parameters of the venous pressure and ΔBV which are monitored(monitored values) are beyond a preset range. Then, if the alarm isissued, the display on the display device 2 is automatically switchedover to an alarm screen α (in the present embodiment, a main alarmscreen A first appears). A device for issuing the alarm may have anyform, either those which output an alarm sound using a speaker or thosewhich turn on an alarm lamp.

First, a case will be described where the alarm is issued since thevenous pressure monitored by the blood purification apparatus (venouspressure detected based on a pressure of an air layer in an air trapchamber of a venous side blood circuit) is beyond the preset range(beyond an upper limit value or a lower limit value).

If the alarm is issued since the venous pressure monitored by the bloodpurification apparatus is beyond the preset range, the screen on thedisplay device 2 is automatically switched over to the main alarm screenA as illustrated in FIG. 3. As illustrated in FIG. 3, the main alarmscreen A displays a cause for the alarm issuing (in this case, assuminga cause where the venous pressure is beyond the preset range) in text.The main alarm screen A continuously performs the various informationdisplays before the alarm is issued (displays of the venous pressure,the dialysate pressure, the ultrafiltration volume integration, theultrafiltration volume setting, the ultrafiltration speed, the IP speed(continuous infusion speed from a syringe using the infusion pump 7),the dialysate temperature, the dialysate flow rate, and the operation orstoppage of the dialysis apparatus, or display of the switch unit forthe retransfusion).

Then, if the input operation is performed by touching the switch unitdisplayed on the main alarm screen A as “details”, the display using thedisplay device 2 is switched over to a detailed alarm screen A1 asillustrated in FIG. 4. The detailed alarm screen A1 displays informationtogether with multiple type information items required for finding thecause for the alarm issuing. In the present embodiment, the detailedalarm screen A1 displays a cause explanation unit 8 indicating itemswhich can be considered as the cause for the alarm; a confirmation itemunit 9 indicating confirmation items required for finding the cause forthe alarm issuing; a monitored value unit 10 indicating a numericalvalue of the parameters of the monitoring subject relating to the bloodpurification treatment (in this case, the monitored value of the venouspressure because it is the alarm relating to an abnormality of thevenous pressure); and a graphic unit 11 indicating a graphicillustrating development of the parameters of the monitoring subjectrelating to the blood purification treatment (in this case, the graphicillustrating the development of the venous pressure because it is thealarm relating to the abnormality of the venous pressure).

Then, in the detailed alarm screen A1 as described above, the multipletype information items required for finding the cause for the alarmissuing (specifically, the cause explanation unit 8, the confirmationitem unit 9, the monitored value unit 10 and the graphic unit 11) aredisplayed together on an identical screen. In this manner, it ispossible to visually and simultaneously check and diversely understandthe multiple type information items relating to the alarm. Accordingly,a health care worker such as a doctor can easily find the cause for thealarm issuing. In the detailed alarm screen A1, as long as the multipletype information items required for finding the alarm issuing aredisplayed together on the identical screen, any of the cause explanationunit 8, the confirmation item unit 9, the monitored value unit 10 andthe graphic unit 11 may be arbitrarily combined and selectivelydisplayed. Alternatively, in addition to the cause explanation unit 8,the confirmation item unit 9, the monitored value unit 10 and thegraphic unit 11, the other type information items relating to the alarmmay be displayed.

Further, in addition to the cause explanation unit 8, the confirmationitem unit 9, the monitored value unit 10 and the graphic unit 11, thedetailed alarm screen A1 displays an operating switch unit 12 whichenables an operation for coping with the cause for the alarm issuing.The operating switch unit 12 illustrated in FIG. 4 is a switch unitwhich enables the operation of stopping the alarm for a predeterminedtime period no matter whether or not the cause for the alarm issuing hasbeen released. After temporarily stopping the alarm by operating theoperating switch unit 12, it is possible to find the cause for the alarmissuing or to cope with the cause for the alarm issuing when necessary.

In this manner, in addition to the displays of the cause explanationunit 8 indicating items which can be considered as the cause for thealarm and the confirmation items (confirmation item unit 9) required forfinding the cause for the alarm issuing, the detailed alarm screen A1displays the numerical value of the parameters of the monitoring subjectrelating to the blood purification treatment (monitored value unit 10)and the graphic illustrating development of the parameters of themonitoring subject relating to the blood purification treatment (graphicunit 11). Therefore, it is possible to simultaneously display multipledifferent type information items relating to the alarm, and thus it ispossible to more accurately find the cause for the alarm issuing. Inparticular, the operating switch unit 12 is a switch unit which enablesthe operation of stopping the alarm for the predetermined time period nomatter whether or not the cause for the alarm issuing has been released.Therefore, it is possible to more quickly perform the operation for thetemporary alarm releasing.

Next, a case will be described where the alarm is issued due toerroneous setting of the infusion pump 7. If the alarm is issued due tothe erroneous setting of the infusion pump 7, the screen of the displaydevice 2 is automatically switched over to the main alarm screen A asillustrated in FIG. 5. As illustrated in FIG. 5, the main alarm screen Adisplays the cause for the alarm issuing in text (in this case,indication that the IP syringe (syringe) is not set, indication that theIP power source is in a disconnected state (that is, OFF), or indicationthat the IP speed (continuous infusion speed from the syringe using theinfusion pump 7) is not set). The main alarm screen A continuouslyperforms the various information displays before the alarm is issued(displays of the venous pressure, the dialysate pressure, theultrafiltration volume integration, the ultrafiltration volume setting,the ultrafiltration speed, the IP speed (continuous infusion speed froma syringe using the infusion pump 7), the dialysate temperature, thedialysate flow rate, and the operation or stoppage of the dialysisapparatus, or display of the switch unit for the retransfusion).

Then, if the input operation is performed by touching the switch unit(for example, the switch unit having a character display that “the IPspeed is not set”) displayed on the main alarm screen A as “details”,the display using the display device 2 is switched over to a detailedalarm screen A2 as illustrated in FIG. 6. The detailed alarm screen A2displays information together with multiple type information itemsrequired for finding the cause for the alarm issuing. In the presentembodiment, the detailed alarm screen A2 displays a cause explanationunit 13 indicating items which can be considered as the cause for thealarm; a confirmation item unit 14 indicating confirmation itemsrequired for finding the cause for the alarm issuing; and a settingvalue unit 15 indicating a setting value relating to the bloodpurification treatment (in this case, the setting value of the IP speedbecause it is the alarm relating to the IP speed).

In the detailed alarm screen A2 as described above, the multiple typeinformation items required for finding the cause for the alarm issuing(specifically, the cause explanation unit 13, the confirmation item unit14 and the setting value unit 15) are displayed together on an identicalscreen. In this manner, it is possible to visually and simultaneouslycheck and diversely understand the multiple type information itemsrelating to the alarm. Accordingly, a health care worker such as adoctor can easily find the cause for the alarm issuing. In the detailedalarm screen A2, as long as the multiple type information items requiredfor finding the alarm issuing are displayed together on the identicalscreen, in addition to the cause explanation unit 13, the confirmationitem unit 14 and the setting value unit 15, the other type informationitems relating to the alarm may be displayed.

Further, in addition to the cause explanation unit 13, the confirmationitem unit 14 and the setting value unit 15, the detailed alarm screen A2displays an operating switch unit 16 which enables an operation forcoping with the cause for the alarm issuing. The operating switch unit16 illustrated in FIG. 6 is a switch unit which enables the operationfor directly coping with the cause for the alarm issuing. It is possibleto achieve the alarm releasing by operating the operating switch unit16, for example, by changing the setting which indicates that the IPwill not be used (that is, the continuous infusion of the anticoagulantwill not be performed by using the syringe). The operating switch may besufficiently configured if the operating switch unit is a switch unitwhich enables the operation for directly coping with the cause for thealarm issuing, and for example, may be those which can change thesetting value of the blood flow rate or the dialysate flow rate.

In this manner, in addition to the cause explanation unit 13 indicatingthe items which can be considered as the cause for the alarm and thedisplay of the confirmation items (confirmation item unit 14) requiredfor finding the cause for the alarm issuing, the detailed alarm screenA2 displays the setting value relating to the blood purificationtreatment (setting value unit 15). Therefore, it is possible tosimultaneously display the multiple different type information itemsrelating to the alarm, and thus it is possible to more accurately findthe cause for the alarm issuing. In particular, the operating switchunit 16 is the switch unit which enables the operation for directlycoping with the cause for the alarm issuing. Therefore, it is possibleto more quickly perform the operation for the alarm releasing.

Next, a case will be described where the operation of the bloodpurification apparatus is stopped and the alarm is issued. If theoperation of the blood purification apparatus is stopped and the alarmis issued, the screen of the display device 2 is automatically switchedover to the main alarm screen A as illustrated in FIG. 7. As illustratedin FIG. 7, the main alarm screen A displays the cause for the alarmissuing in text (in this case, indication that the bypass connector ispositioned in the connector receiver 5, and indication that the dialysisis stopped (that is, the dialysis treatment is stopped)). The main alarmscreen A continuously performs the various information displays beforethe alarm is issued (displays of the venous pressure, the dialysatepressure, the ultrafiltration volume integration, the ultrafiltrationvolume setting, the ultrafiltration speed, the IP speed (continuousinfusion speed from a syringe using the infusion pump 7), the dialysatetemperature, the dialysate flow rate, and the operation or stoppage ofthe dialysis apparatus, or display of the switch unit for theretransfusion).

Then, if the input operation is performed by touching the switch unit(for example, the switch unit having a character display that “thebypass connector is positioned in the connector receiver”) displayed onthe main alarm screen A as “details”, the display using the displaydevice 2 is switched over to a detailed alarm screen A3 as illustratedin FIG. 8. The detailed alarm screen A3 displays information togetherwith multiple type information items required for finding the cause forthe alarm issuing. Therefore, in the present embodiment, the detailedalarm screen A3 displays a cause explanation unit 17 indicating itemswhich can be considered as the cause for the alarm; a confirmation itemunit 18 indicating confirmation items required for finding the cause forthe alarm issuing; and an image 19 for indicating confirmation itemsrequired for finding the cause for the alarm issuing or a coping methodwith respect to the cause for the alarm issuing. For example, the image19 shows the entire blood purification apparatus (dialysis apparatus) byusing an image, and enables the cause for the alarm issuing or a portionrelating to the finding of the cause for the alarm issuing to bespecified and enables the details to be visually checked. Therefore, theimage 19 may be either a still image or a video image.

Then, in the detailed alarm screen A3 as described above, the multipletype information items required for finding the cause for the alarmissuing (specifically, the cause explanation unit 17, the confirmationitem unit 18 and the image 19) are displayed together on an identicalscreen. In this manner, it is possible to visually and simultaneouslycheck and diversely understand the multiple type information itemsrelating to the alarm. Accordingly, a health care worker such as adoctor can easily find the cause for the alarm issuing. In the detailedalarm screen A3, as long as the multiple type information items requiredfor finding the alarm issuing are displayed together on the identicalscreen, in addition to the cause explanation unit 17, the confirmationitem unit 18 and the image 19. the other type information items relatingto the alarm may be displayed.

In this manner, in addition to the cause explanation unit 17 indicatingthe items which can be considered as the cause for the alarm and thedisplay of the confirmation items (confirmation item unit 18) requiredfor finding the cause for the alarm issuing, the detailed alarm screenA3 displays the image 19 for indicating the confirmation items requiredfor finding the cause for the alarm issuing or the coping method withrespect to the cause for the alarm issuing. Therefore, it is possible tosimultaneously display the multiple different type information itemsrelating to the alarm, and thus it is possible to more accurately findthe cause for the alarm issuing. In particular, the display of thedetailed alarm screen A3 includes the image for the confirmation itemsrequired for finding the cause for the alarm issuing or the copingmethod with respect to the cause for the alarm issuing. Therefore, it ispossible to visually understand the confirmation items or the copingmethod, and thus it is possible to more easily and accurately use theconfirmation required for finding the cause for the alarm issuing or thecoping method.

According to the present embodiment, the display device 2 can switch anddisplay the plurality of screens including the alarm screen α displayeddue to the alarm issuing. The alarm screen α (in the present embodiment,the detailed alarm screen) displays the information together with themultiple type information items required for finding the cause for thealarm issuing. Accordingly, a health care worker such as a doctor candiversely understand the information relating to the alarm, and thus itis possible to easily and quickly find the cause for the alarm issuing.According to the present embodiment, in the alarm screen, whereas themultiple type information items required for finding the cause for thealarm issuing are displayed together, the other information which doesnot relate to the alarm is not displayed. In this manner, a worker canconcentrate his or her senses on finding or coping with the cause forthe alarm issuing.

Hitherto, the present embodiment has been described, but the presentdisclosure is not limited thereto. For example, the screen of thedisplay device may be set to exclusively perform the display and amechanical switch or the like may be arranged near the screen so as toenable the input operation. However, if the display device 2 as in thepresent embodiment is the touch panel which enables a predeterminedinput by touching the switch unit displayed in a desired position on thescreen, and if the alarm screen displays the operating switch unit whichenables an operation to cope with the cause for the alarm issuing, it ispossible to eliminate a need for an operating device separated from thedisplay device 2, thereby enabling a configuration of the bloodpurification apparatus to be simplified.

In addition, the main alarm screen in the alarm screen α may be omittedand if the alarm is issued, the detailed alarm screen may be directlyswitched over to be displayed. Alternatively, other displays such as thenumber of the alarms issued may be added to the display on the alarmscreen. In addition, the alarm screen performs the display as describedin the above embodiment, and may display the shortcut switch unit whichcan switch to the operation screen capable of performing the operationfor coping with the cause for the alarm issuing. In this case, even aperson who is unfamiliar with the switching operation of the displaydevice 2 can smoothly switch to the operation screen for the alarmreleasing.

Furthermore, the display of the multiple type information items requiredfor finding the cause for the alarm issuing can be individually setdepending on the patient. For example, for a dynamically moving patient,a patient constantly having a high venous pressure or a patientconstantly having a low venous pressure, it is possible to change thealarm screen depending on the patient's inherent conditions (types ofdisplays, the layout and size of each display are change depending onthe patient). In this case, it is possible to display the alarm screenwhich matches the condition for each patient.

In addition, in the present embodiment, the display device 2 is appliedto the hemodialysis apparatus in a hemodialysis (HD). However, insteadof this, the display device 2 may be applied to a blood purificationapparatus which can perform the other blood purification treatment (forexample, treatment using hemodiafiltration (HDF), hemofiltration (HF) orslow continuous hemodiafiltration (CHF)).

If a display device can switch and display a plurality of screensincluding an alarm screen displayed due to alarm issuing, and if a bloodpurification apparatus allows the alarm screen to display informationtogether with multiple type information items required for finding acause for the alarm issuing, the display device can be applied to thosewhose outer shape is different or those which have the other addedfunctions.
